I have an '02 Sunfire 2.2 OHV and I have had P0122 (Throttle Pos Sensor) and C1275 (PCM requested ETS to be Disabled) codes come up twice after sitting in extreme traffic in the last two weeks. I think it was raining both times. There did not seem to be any problems, just the TCS light and the engine light came on. The Traction light did not come on the next time I started the car. I cleared the codes and they came back only after sitting in major traffic again.

Has anyone else had these codes? Can one cause the other? I don't want to just change the TPS if the PCM is the problem. I am also worried because I replaced the steering column a week before this started happening and I don't know if this could be a symptom of a short in the column.
